The quality of biology education in the secondary school is dependent on biology teachers, who develope their abilities through preservice and inservice training. The contents of text materials for career/credentialed inservice training of biology teachers published at each province in Korea, were analysed to examine the effectiveness of the programs. The text materials were very different exept that they were composed of three domains of liberal arts, pedagogy, and major, and that training time allocated each domain was similar according to the province. And the contents of text materials were not sufficient to develope abilities of biology teachers needed ti teach effectively in the class and the lab as followers; 1) the contents of major subjects were determined not by necessities of biology teachers but by lecturers; 2) new science teaching methods. skills, and knowledges for lab teaching and research methods in science education were deficient in most text materials. Therefore curricula and text materials for inservice training of biology teachers should be developed.
